Fig. 4. VAR3 protein. (A) Alignment of VAR3 (accession number ATG517790) with three related Arabidopsis proteins (AAG51125, AAG52346 and AAF79711). Conserved residues are in black and similar residues in gray. Arrows indicate intron sites and the double arrow the Ds insertion site. (B) Top: similarity between VAR3 zinc-finger domains (ZnF1 and 2) with those from yeast (ScARP, P32770) and human nucleoporins (HsLUCA15, P52756; HsNUP358, P49792). Bottom: similarities defining the novel repeated regions of VAR3.
